As far as i'm concerned any advantage without actually cheating is fair game, No different than defenders whispering in the forwards ears trying to get a reaction or vice versa, Imagine Fellaini doing that with his hair lol

Fellaini is a funny fella at the minute, not sure whats happening with him and the Everton fans.They were booing him the other day, against Wigan, although his attitude did look a little suspect during the game.Stormed off after being substituted too. Probably didn't help a few weeks back when he said he wanted to join Chelsea
